Atmospheric thermodynamics

Procedure: Before beginning each experiment, remove all clutter from the workstation and read the directions for the experiments thoroughly. Part 1: Warm slightly more than 300 mL of water to approximately 70 degrees Celsius. Measure out 150 mL of water into the coffee cup calorimeter. Take the temperature of this water in the coffee cup calorimeter once it has reached a steady temperature. Then, add an ice cube approximately the size of a large marshmallow. Stir the ice and water and measure…

and security. In contrast, by expressing the laws of thermodynamics, it is stressed that through the process of discovering a balance, obstacles can be achieved. Thermodynamics highlights the stream of science attentive to heat and conversions to different forms of energy and work. Not only does the thermodynamic state define volume, temperate and pressure, it will contain heat sources giving a capacity, and change state. The idea of thermodynamics is for the system to adjust itself back into…

Humans are bound by science. In everything we do, scientific laws have been put into place to help us come to terms with our existence on this planet. One of the most important of these laws is the second law of thermodynamics, which is also known as entropy. In thermodynamics, entropy is a “quantity representing the amount of energy in a system that is no longer available for doing mechanical work” (Vocabulary, 2016), while in a philosophical sense entropy is the migration from order to chaos.…

Crayfish are freshwater crustaceans that use their claws called chelipeds,for warning off predators. When frightened, these crayfish lift their chelipeds to make threatening gestures, all while moving backwards or staying still. We examined how long it would take for crayfish to calm down once removed from the water and if the temperature had any influence to this observation. To do this, we placed two crayfishes in room temperature water and another two in colder water for an interval of five…

The Effect of Cellular Respiration at Low and High Temperatures Introduction Cellular respiration can include two processes, aerobic respiration and anaerobic respiration. The main purpose of cellular respiration is to breakdown sugars into smaller structures so that the cell can use it as energy (Reece, et al. 2014). The main concept of the respiration lab is aerobic respiration. This is the process that organic compounds will be degraded from oxygen to produce water, carbon dioxides, and…

surface area vs rate of time Introduction: In the investigation an experiment is conducted investigate if the breaking of alka seltzer into ½, ¼ and none effect the time it dissolves. The context of the problem is the time it dissolves to have the medicine show its effect. This problem exist in real life as people take alka seltzer to relief heartburn, acid digestion and stomach aches. This experiment would benefit society because it informs the society the better way of consuming medicine or…

Climate change is clearly evident in the world around us and it is having and will continue to have a major impact on our lives. Therefore, it is very relevant to analyze the changes in climate that have occurred in Howard County, Maryland such as the significant changes in mean precipitation and timing of precipitation, winter temperature and the summer precipitation. Furthermore, it is crucial to understand that many of these changes will be clearly seen in the relatively near future if…

“Are you alright?” my mother usually asks me that question whenever I get sick. Then she would touch my forehead and neck to check if I’m hot. She’d rush to our medicine cabinet and get the mercury thermometer, shakes it, and puts it in between my armpit. After two to three minutes, she’d get it and read what it says. “You’re sick, 39 degree Celsius” Mom said. Since then, I have asked my mother to teach me how to read the thermometer. Whenever there’s a family member who gets sick, it would be…

history, and human comprehension. When you take a step backward and genuinely contemplate archeological discoveries, you will uncover no evidence for evolving creatures but only many missing links. If you investigate science, especially the laws of thermodynamics, you will gather that evolution disregards all the guidelines of how the universe truly functions. When using our multifaceted brains and observing nature, we ought to acknowledge that these curiosities could not have materialized by…

Introduction: Enzymes have a huge effect on the human body and other organisms. Enzymes are catalysts that are used to accelerate the reaction process by lowering the activation energy. For this experiment the catechol oxidase was extracted from potatoes. The enzyme is called catechol oxidase because the oxygen is reacting to catechol. Catechol oxidase causes the browning of the fruits and vegetables because the compound is toxic to the bacteria. The purpose of this experiment is to…
